Description

The invention relates to a handlebar assembly for a vehicle having at least one in the vehicle longitudinal direction axle guide, attached to the wishbone transversely to the vehicle longitudinal axis axle, a chassis fixed mounted support for pivotal mounting of the wishbone by means of a through the support and the wishbone transversely to the vehicle longitudinal direction passing bolt, adjusting means for displacing the wishbone relative to the support in the vehicle longitudinal direction, and positioning means for fixing the longitudinal position of the wishbone relative to the support.

The invention further relates to a method for moving a wishbone in the vehicle longitudinal direction of a vehicle, wherein the wishbone is part of a extending in the vehicle longitudinal direction arm assembly, crossing a transverse to the vehicle longitudinal axis axle body of a vehicle axle, on a fixed chassis support by means of a through the support and the Achslenker is transversely mounted transversely to the vehicle longitudinal direction bolt passing, is displaceable by means of adjusting relative to the support in the vehicle longitudinal direction, by means of positioning means relative to its longitudinal position relative to the support is fixable.

The tracking of commercial vehicle trailers, or the alignment of axle links along the vehicle longitudinal direction, is generally performed by eccentric arrangements or track adjustment plates. Such solutions usually require the additional installation of eccentric discs or track adjustment plates on the wishbone or between the wishbone and the chassis-fixed support. The wishbone is pivotally mounted within the support. When setting the track through eccentric discs and track adjustment plates, it is often necessary to move the stuck components by jerky movements such as a hammer blow. The eccentric disk or track adjustment plate diverts the generated movement to the axle guide, and effects a displacement of the axle guide along the vehicle longitudinal direction. In addition to the considerable installation effort in the attachment of additional components and the associated cost increase, can result from the impact stress material damage. These may be, in particular surface damage such as paint flaking including increased risk of corrosion or the impact-induced loss of component section. In US 6,550,795 a mechanism for aligning a trailing arm and an attached transverse axis in the vehicle longitudinal direction is shown. On the vehicle chassis, a support for the trailing arm is attached, which carries a shock absorber, an axle body and an air spring, which in turn is connected at its top to the vehicle chassis. The support is provided with slots opposite to an opening in the trailing arm. The attachment of the trailing arm end to the support is accomplished via a bolt with washer and nut. Between the trailing arm end and the support is an eccentric disc with several holes. In this case, a central, oval hole opening is penetrated by said bolt. This is still engaged with the openings of the support and the trailing arm in engagement. As far as the side wall of the support, the eccentric disk projects beyond the fact that the eccentric disk can be gripped and rotated via a tool engaging in two holes at the same time, as a result of which a longitudinal displacement of the trailing arm is indirectly effected. The tracking of a wishbone on such eccentric disc arrangement is associated with an increased design, assembly and cost.

A similar adjusting device for tracking is shown in US 2008/0036167 A1. For adjustment, the bolt on the outside of the support is in contact with two washers. The washer each has an enlarged upper portion and a narrower lower portion. By attack of an actuating tool in a hexagonal opening at the lower portion of the disc, this can be rotated and the trailing arm together with bolt is thus moved in the vehicle direction. Also in this arrangement for tracking adjustment, it is disadvantageous that with the washer, an additional component for moving the wishbone is needed. This also leads to increased construction, assembly, maintenance and cost.

The invention is based on the invention to provide a handlebar assembly for a vehicle with at least one extending in the vehicle longitudinal direction control arm, which allows a precise tracking even with a simple, requiring few components construction, and at the same time gentle on materials.

To solve this problem, a handlebar assembly for a vehicle with the features specified in claim 1, and a method for stepless displacement of a wishbone with the features of claim 22 is proposed. In such a link assembly according to the invention, the wishbone is pivotally mounted on a chassis-fixed support via a hinge pin. The hinge pin leads through an opening in the wishbone and openings in the side walls of the support and is secured by a nut. The bolt, nut, opening on the support and an apertured washer form positioning means for fixing the longitudinal position of the wishbone. Furthermore, the wishbone carries a transverse to the vehicle longitudinal axis axle body, a suspension and possibly shock absorbers. The tracking adjustment or the displacement of the axle guide in the vehicle longitudinal direction via adjusting means. These consist on the one hand of at least one attack surface for a lever tool on the wishbone or a achslenkerfesten component, and on the other hand from at least one chassis-fixed support surface. The two surfaces are arranged so that both at the same time the lever tool can be applied so as to apply a displacement force in the vehicle longitudinal direction.

The attack surface is preferably located on a recessed in the axle guide recess. Also, the attack surface can be formed by integrally formed on the wishbone lugs or permanently connected to the wishbone components.

The chassis-fixed support surface is preferably formed directly on the support. Since the adjusting means are direct components of the wishbone or the support, it is not necessary to mount separate components solely for tracking. This avoids unnecessary work steps and saves component and labor costs. The aforementioned adjusting means can be produced, for example, in the production steps required anyway in the production of the axle guide or during forming or embossing of the support.

Thus, by means of a lever tool can be attacked simultaneously on one of the attack surfaces on the wishbone or a achslenkerfesten component and a support surface on the support and upon application of a leverage longitudinal displacement of the wishbone can be effected either in each of the two directions of the vehicle longitudinal axis, it is advantageous the attack surface and the support surface in such a way that they are divided into two and each composed of a first partial surface and a second partial surface. The faces are directed in the vehicle longitudinal direction, however, have in opposite directions. This can be advantageous for as effortless manual tracking as possible with a favorable lever arm. The two faces of the attack surface may be facing away from each other. The opposite faces of the attack surface can be formed for example by a recess on the wishbone. This is particularly advantageous for cost-effective production, because such recesses can be defined in the casting process of the axle guide.

For tracking adjustment, the lever tool is supported on the one hand on a partial surface of the engagement surface and on the other also on a partial surface of the support surface. In an embodiment of the attack surface with faces facing away from each other, the lever tool is located on a partial surface of the support surface, which points in the opposite direction of the partial surface of the attack surface. However, the two faces of the support surface in this case are facing each other.

In a further embodiment of the invention, the two faces of the attack surface may also face each other. Such an engagement surface may be a recess, an attachment, or a hook formed or attached to the wishbone. In this embodiment, the lever tool is also supported on a partial surface of the engagement surface and on a partial surface of the support surface. The standing in contact with the lever faces are diagonally to each other. Accordingly, the partial surfaces of the support surface facing each other.

By leveraging the wishbone can be maneuvered along the vehicle's longitudinal axis both forward and backward. The forces generated by levers act on the attack surface and the support surface in the opposite direction.

It is further advantageous in this regard, if the attack surface and the support surface have a distance of 1 cm to 5 cm transverse to the vehicle longitudinal direction. In this way, a displacement of the axle guide in two directions is possible using a not too large and therefore still easy to handle for the fitter lever tool.

Contrary to the prior art, it is not necessary to include additional components in the construction, resulting in increased robustness and reduced material wear in tracking. Because the attack surface and the support surface each consist of only two partial surfaces, the construction is significantly simplified compared to Justierscheiben- or Exzenteranordnungen. It is advantageous to design the attack surface in the form of a recess or a neck on the wishbone. In this case, such a recess may have almost any shape, as long as it has two faces. The outside of a recess can serve as a partial surface of the attack surface. The faces of the attack surface must therefore not necessarily be within the recess.

It is particularly advantageous if the recess has an edge-shaped or at least partially circular contour. Such a contour allows the clear subdivision of the attack surface in two sub-areas. As a result, the construction according to the invention is simplified in comparison to known from the prior art eccentric, screw or Klemmanordnungen. Such a recess can be formed in an already required production step, such as when casting the wishbone, or in a later step by milling or drilling. It is also possible to provide only recesses in a penetrated by a bolt, tightly clamped with a nut washer. Such recesses can also be attack surface for a lever tool. The corresponding support surface for the lever tool is preferably a recess in the support. The attack surface can also be formed by a projection in the form of a molded onto the wishbone during casting projection. Even on the wishbone existing bolts or nuts can form the attack surface. It is advantageous if such an approach points in the direction of the support. It may be one or more such projections, bolts or nuts are in close proximity to each other and thus form two partial surfaces preferably. It is conceivable that the abovementioned projections, bolts or nuts are components already present on the wishbone with a fastening or tensioning function. Thus, existing components for tracking adjustment are used to provide the adjustment. As a result, costs and additional installation costs can be reduced.

In a further preferred embodiment, the engagement surface can also be formed by a hook arranged on the wishbone. In this case, the hook is either formed during casting of the axle guide or fastened in a later method step to the wishbone, for example by welding, riveting, clamping or screws. It is advantageous to form the hook as the axle guide in the direction of travel extending extension. The hook forms a part-circular or part-arc-shaped opening from its underside. At this opening is the attack surface for conditioning of the Lever tool. The part-circular or part-arc-shaped opening has a circumferential extent of the attack surface of at least 180 °. It is thereby achieved that at each abutment position of the lever tool on a partial surface of the engagement surface, this partial surface faces another partial surface of the engagement surface. The use of such a hook as part of the adjustment is advantageous because it undergoes some protection against external influences by its arrangement on the wishbone within the support housing.

The arranged in the region of the support hook is characterized in a preferred embodiment in that it has a smaller width than the rest of the wishbone. As a result, an unnecessary broadening of the link assembly is avoided by adjusting means required for the tracking adjustment. Due to the smaller width of the hook and the distance to the support is increased, whereby damage to the support, such as slipping of the lever tool, are avoided.

In addition, there is the possibility to attach to such a hook other vehicle parts. For example, a shock absorber or an axle lift can be hinged to the outside of the hook or to the top. In such an embodiment, the shock absorber or the axle lift is protected by the side walls of the support from external influences such as splashing water, road salt and other impurities.

The chassis-fixed support surface is preferably designed as a recess or as an approach to the support. In this case, both the recess and the approach may be formed either on one of the side walls of the support or on the front wall. In particular, an arrangement on the side wall has been found to be particularly practicable. Since the recess or the approach are preferably formed from the material of the support, the use of additional components is avoided, and thus saves cost and installation effort. In addition, the tracking adjustment is simplified due to the unnecessary installation of additional components.

The recess on the support can have either an edge-shaped or an at least partially rounded contour. An edge-shaped contour may mean that it is a trigonal, tetragonal or pentagonal contour. It is preferred if the recess has a circular or semicircular contour, wherein the embodiment with a recess of circular contour is particularly preferred. This can be implemented, for example, in a punching or drilling process. The Support surface can thus be formed during production or subsequently.

In a further embodiment, the projection on the support may be a projection formed by embossing the support plate or else a pin already present on the support plate and a nut. It is particularly preferred if several such approaches are opposite to form two mutually facing partial surfaces of the support surface. By using existing vehicle parts as a support surface both the installation and cost is reduced, as well as the tracking significantly simplified.

The positioning means and adjusting means located on the support can be arranged at a distance from each other. In this case, the recess or the projection on the support can be located on circumferentially arbitrary positions relative to the positioning means. It is advantageous if the approach or the recess is located on the support in the vehicle longitudinal direction approximately opposite the recess or the neck on the wishbone. Since the positioning and adjustment are spaced apart from each other, the risk of damage to the positioning is minimized when moving the wishbone by applying a lever tool on the adjustment. Positioning and adjustment means can be attached to both the inner side wall and the outer side wall of the support. The inner side wall of the support is located closer to the vehicle center than the outer side wall of the support.

An arrangement on the support front side is possible. This results in a significantly increased variability in the production and assembly of the axle guide on the chassis-fixed support. The track adjustment can be made flexible depending on the design or need.

From the prior art are known as positioning the bolt on the support fixing nuts together with washers and track adjustment plates with at least one opening. To save component costs, it is advantageous if only a round washer and no track adjustment plate is used. As a result, the fastening mechanism of the bolt is simplified.

The washer may be provided with a recess spaced from the bolt. This forms the faces of an attack surface for the lever tool. Due to the fixed tension with the wishbone, it is possible to move the wishbone in the vehicle longitudinal direction with a lever tool that simultaneously acts on a support surface, in this case a part of a recess in the chassis-fixed support. Further details and advantages of the invention will become apparent from the following description of the accompanying drawings, in which embodiments of the link assembly according to the invention and the method for stepless displacement of a wishbone are shown.

Embodiment of the invention. On the underside of the vehicle frame of a truck trailer or -Augliegers bar assemblies on supports 1 are fixed to the chassis mounted on the left and the right side of the vehicle, the top 2 of the support 1 is preferably welded to the side rail of the vehicle frame. As can be seen from FIG. 1, the support 1 supports a wishbone 3 pivotably on a bolt 4.

The bolt 4 is guided by a transverse to the vehicle longitudinal axis L through opening 5 on the axle guide 3 and through openings in the respective two side walls 6, 7 of the support. Furthermore, the threaded bolt 4 is fixed to the side wall 6 of the support 1 via a nut 10 together with a washer 1 1.

The support 1 according to the invention is composed of two side walls 6, 7 and a front wall 8 connecting the side walls 6, 7. A side wall 7 is transverse to the vehicle longitudinal direction further inside the vehicle than the other side wall 6. From the prior art supports 1 are known, in addition to the bolt 4 through the support side wall 6 leading opening 16 have a material projection 15, for vertical guidance of a track adjustment plate 12 serves. In the from the state of the art known embodiment of the link assembly of FIG. 1 is achieved by a blow from above or below the track adjustment plate 12, a displacement of the axle guide 3 in the vehicle longitudinal direction. The bolt 4 is guided by a befindliches on the support 1 and located on the track adjustment plate 12 slot. The longitudinal axes of the two slots are transverse to each other.

The axle guide 3 is z. B. produced in one piece in a casting process, while the support 1 is formed from sheet metal. As shown in FIG. 1, material protrusions 15 on the support 1 for guiding the tracking plates 12 are known from the prior art.

The axle guide 3 may have a half-shell 25 at its rear end facing away from the support 1, in order to receive an axle body (not shown) extending transversely to the vehicle longitudinal axis L of a vehicle axle. Furthermore, the wishbone 3 in the immediate vicinity of the half shell 25 has a lug 21 for a shock absorber.

As Figure 2 shows in a first embodiment of the invention, located next to the bolt 4 leading, slot-shaped opening 16 of the support 1 at least one further recess or opening 22 in the side wall 6 of the support 1. Through this opening 22 can pass through a Lever tool 20 are engaged in the inner column area. The opening 22 may be located at any position relative to the bolt 4 leading opening 16, as long as both openings 16, 22 are spaced from each other. The guided through the opening 16 and the slot bolt 4 is, as shown in FIG. 3, clamped with a washer 11 and a nut 10 on the side wall 6 of the support 1.

The washer 1 1 can be round, square or rectangular cross-sectional contour. Figures 1 1, 12 and 13 show optional forms of washers which allow a lever tool to pass through the washer n. As can be seen in FIGS. 9 and 10, a lever tool 20 engages in recesses 22 of the support in this case. In this embodiment, the recesses of the washer 1 1 form an engagement surface 31, 32 for the lever tool 20th

According to the first embodiment (FIG. 4) of the invention, in addition to the opening 22 in the support side wall 6, there is also a recess 9 on the axle guide 3. In this embodiment, the opening 22 in the support 1 and the recess 9 in the axle guide 3, with respect to the vehicle longitudinal axis L, spaced apart from the bolt 4 is arranged. The Recesses 9, 22 may be formed in the region of the rear axle link section 40 or the front axle link section 41.

The recess 9 on the axle guide 3 forms a two-part engagement surface 31, 32 for the lever tool 20. This engagement surface 31, 32 is divided into a first partial surface 31 and a second partial surface 32, wherein both partial surfaces 31, 32 are directed in the vehicle longitudinal direction, but in each other have opposite directions. A partial surface 32 of the engagement surface 31, 32 is formed in this embodiment of the end face 38 of the axle guide 3, while the other part surface 31 is formed by an inner surface of the recess on the axle guide 3. The opening 22 in the region of the side wall 6 of the support 1 forms the support surface 33, 34 for the lever tool. This support surface 33, 34 has two facing partial surfaces 33 and 34th

When planting the lever tool 20 at the same time on one face 34 of the support surface and a part surface 31 of the attack surface, and then a force in the direction of the vehicle rear by force exerting pivoting of the lever tool 20, the wishbone 3, according to the arrow in Fig. 4, in the direction move to the front of the vehicle, whereby the vehicle axle is moved accordingly to the track adjustment. The bolt 4 must be in the untensioned state.

In this embodiment, the lever tool 20 bears against an inner surface of the recess 9 on the axle guide 3, wherein the recess has the function of a first partial surface 31 of the engagement surface 31, 32. The support surface forming opening 22 in the support, according to the first embodiment of the invention on both side walls 6, 7 of the support 1, or even on one of the two side walls 6, 7 may be formed. An engagement with the lever tool 20 through the underside of the support 1 is possible.

As can be seen from FIG. 5, the axle link 3 shifts with the simultaneous application of the lever tool 20 on the first part surface 33 of the support surface 33, 34 and the second part surface 32 of the engagement surface 31, 32 and levers in the direction of the arrow in the direction of the vehicle end. The second partial surface 32 of the engagement surface 31, 32 in this embodiment is the end surface 38 of the axle guide 3.

The bolt 4 is surrounded by a cylindrical steel rubber bush, which is based on the bolt from the inside to the outside of a spacer 35, a steel bushing 36 and a rubber ring 37 composed. The axle guide 3 can in a located behind the steel rubber bushing rear axle link section 40 and a front of the Stahlgummibuchse front axle link section 41 are divided, wherein the front portion 41 and the rear portion 40 are a one-piece component. The steel rubber bushing extends within a the axle 3 penetrating opening. In a second embodiment, the two-part engagement surface 31, 32 formed by both inner surfaces of the recess 9 in the axle guide 3. For maneuvering the axle guide 3 in the vehicle longitudinal direction, the lever tool 20 according to FIG. 4 bears on the first part surface 31 of the engagement surface and on the second part surface 34 of the support surface. The lever and direction of movement is indicated by arrows. In addition to FIG. 4, this second embodiment is also represented by FIG. There, the abutment position and the lever direction of the lever tool 20 opposes the abutment positions shown in FIG. According to the arrow direction of the wishbone is moved in the direction of the vehicle rear side. Also in this embodiment, the lever tool 20 can pass through the support 1 from both side walls 6, 7.

According to a third embodiment (FIGS. 7 and 8), the engagement surface 31, 32 can also be realized by lugs 21 facing the support 1, such as projections, nuts or bolts. In this case, it is only of relevance that two partial surfaces 31, 32 of the projections lift off from the material surface of the axle guide 3 in the direction of the support 1, and that the partial surfaces 31, 32 face one another. Such lugs 21 can be located on the left-hand side as well as the right-hand side of the bolt 4 on the axle guide 3. In Figure 7, the lugs 21 are located on the rear axle link section 40, but may, as already mentioned, also be located on the front axle link section 41. In this embodiment as well, as shown in FIGS. 7 and 8, a lever tool 20 applied from the outside can engage a partial surface of the engagement surface 31, 32 and a partial surface of the support surface 33, 34 and the axle link 3 can be identified by the axle link 3 shown in FIGS Move the lever directions forwards or backwards along the vehicle's longitudinal direction.

The main power flow at the handle of the lever tool 20 and the direction of movement of the axle guide 3 are opposite in the first embodiments. The lugs 21 on the axle guide 3 may be formed on both sides or on only one side of the axle guide 3. The same applies to the recesses in the support 1.

In a further embodiment, the engagement surface 31, 32 for the lever tool 20 is not as in the embodiments described above on Achslenker 3. The attack surface 31, 32 is located in a recess of the washer 11. This can according to the variants shown in FIGS. 1 1, 12 and 13 include a plurality of recesses for forming the engagement surface 31, 32. By configuring a plurality of recesses in the washer, preferably on the left and right sides of the bolt 4, a total of greater adjustment range is achieved compared to the other embodiments. The tracking is thus possible over a larger area along the vehicle longitudinal axis.

As can be seen in FIG. 9, the lever tool engages through a recess of the washer 11 into a recess 22 in the support 1. The recess in the support 1 forms a partial surface 33 of the chassis-fixed support surface 33, 34, and may have the shape of a slot 47. In order to maneuver the wishbone to the rear, in the direction of the vehicle rear side, the lever tool 20 bears against the first part surface 31 of the engagement surface 31, 32. The washer 1 1 is displaced together with bolt 4 and wishbone 3 relative to the support 1 to the rear.

According to this embodiment, the second part surface 32 of the engagement surface according to FIG. 10 is located in a second recess of the washer, on the right side of the bolt 4. This can also be effected by turning a washer 1 1 with only one recess, such as a washer according to FIG. 13. The second part surface 34 of the support surface 33, 34 is located in a further recess 22 of the support 1. When lever according to the arrow in Fig. 10, the wishbone 3 would be moved relative to the chassis and positionally fixed support 1 in the direction of the vehicle front. The recesses in the washer 11 and the support 1 may be formed on both sides of the axle guide 3, more precisely on both side walls 6, 7 of the support. 1

9 and 10 conditionally adjacent to the opening 16 for the bolt 4 at least two further openings or recesses in the washer 1 1. The figure 11 shows a variant of a washer 1 1, wherein the washer 1 1 in the middle of a Opening 16 has, which penetrates the bolt 4 when mounted. The outer contour of the washer 11 is zigzag in cross-section. Extensively alternating recesses 45 and projections 46 alternate. The engagement surface 31, 32 is one of the side surfaces formed by a recess 45. In such a configuration of the washer, the lever tool 20 can engage at two sides of the washer 11. As can be seen from FIGS. 9, 10 and 11, this makes a larger adjustment range accessible during the tracking adjustment. According to Fig. 12, it is also possible to use a square washer 1 1 with rounded corners. Left and right sides of the washer 1 1 in the center penetrating bolt 4 are openings through which the lever tool 20 can reach through. Due to the configuration of the openings 22 in the support as a vertical slot 47, a vertical Abwinkein the lever tool 20 is possible.

The same can be achieved with a washer according to FIG. 13. There is the side of a main opening 16 of the washer 1 1, a hole pattern 48, which allows attachment of the lever tool 20 in different vertical positions. Due to the additional horizontal extension of the perforated grid 48, the lever tool 20 can also assume different horizontal positions. In the untensioned state, the washer can be rotated by 180 ° and thus allows engagement in a second opening in the support 1. In a further embodiment of the invention according to FIG. 14, the support surface 33, 34 can also be formed by projections 50 on the support 1, which project in the direction of the axle guide 3, are formed. In this case, the projections 50 have two partial surfaces 33, 34 of the support surface 33, 34 form, which allow a lever tool 20, either on the first 33 or the second 34 of the facing faces 33, 34 of the support surface 33, 34 abut. In the embodiment according to FIG. 14, the lever tool 20 does not grip from the side through the support 1 as in the previously described embodiments, but contacts the first partial surface 33 or second partial surface 34 of the support surface 33, 34 from below. In this embodiment, the engagement surface 31, 32 on the wishbone 3 can be realized by projections such as projections, nuts, bolts or recesses previously shown embodiments. Decisive is the attachment of the support surface 33, 34 on the inside of the side wall 6, 7 of the support 1. When tracking setting the lever tool 20 is located on one of the engagement surfaces 31, 32 of the lugs or recesses. Furthermore, the lever tool 20 is supported on one of the support surfaces 33, 34 on the inside of the support 1. Depending on the direction of the lever tool 20, the axle link 3 is moved forwards or backwards along the vehicle longitudinal direction.

It is also possible, as shown in Fig. 15, form a known from the prior art axle guide 3, so that the engagement surface 31, 32 for the lever tool 20 in the form of a hook 55 has (Fig. 16). Such a hook 55 is in one piece according to the invention molded by casting to the front end of the axle guide 3 or separately attached to the front end of the axle guide 3.

The part-circular or part-arc-shaped opening 56 with the pitch center 14 has a radial extent of the attack surface of at least 180 °.

The hook 55 forms a part-circular or partial arc-shaped engagement surface 31, 32 for the lever tool 20, wherein the part-circular or part-arcuate opening 56 in lateral contour of the engagement surface 31, 32 has a radial extent of at least 180 °, so that the attack surface 31, 32 in a first part surface 31 and a second part surfaces 32 can be divided, which face each other.
